Can't connect externally to mumble

I'm trying to run a mumble server on the default port at this ip 99.75.162.81 and I am getting nothing
I used the linux turnkey solution I can connect over lan but not wan
I have forwarded the port I verified this with minecraft which works just fine over wan.
Can anyone tell me what I've done wrong?
edit:
maybe I should call @wendell
any ideas?

Does Linux turnkey use SELinux or have an Active firewall?

I do have selinux but unconfigured and I have no active firewall on my box
edit:
selinux is not installed apologies

Well, from what I see, try resetting your router and port forward again, if it is working over LAN there should be something wrong between the server and the router, another thing to look for is there might be a LAN only option.

rebooted the router and the box still nothing
does att block port 64738?

edit:

FIgured out more (I've got vms running windows and linux)
the linux vm can connect and auto detects the lan murmur server
The windows vm just craps itself and doesn't auto find the lan murmur server (works fine if you point it at it)(big surprise windows being an issue once again)
